Lake Water
批注[Ul]: So much指代前文，说 water是怎么enter怎么leave的，所 以正确答案是D。注意B貌似也对， 但代入之后是有问题的，因为water 不是obvious的，明显的是信息，因 此so much不仅仅指代它的前句，还 指代了前一句的前一句，正确答案是
D
[1. The phrase So much in the passage refers toj
the negative effects of overland flow, rain, and evaporation on river water levels
water that a lake loses to outflowing rivers, to the lake bed, and to evaporation
the importance of rivers to the maintenance of lake water levels
the information given about ways that water can enter or exit a lake
Where does the water in a lake come from, and how does water leave it? Water enters a lake from inflowing rivers, from underwater seeps and springs, from overland flow off the surrounding land, and from rain falling directly on the lake surface. Water leaves a lake via outflowing rivers, by soaking into the bed of the lake, and by evaporation. So much is obvious.
[2. The word gains in the passage is closest in meaning to]
results
increases
resources
savings
|3. Which of the following can be inferred from paragraph 2 about the movement of water into a lake?]
Heavy rain accounts for most of the water that enters into lakes.
Rainfall replaces approximately the amount of water lost through evaporation.
Overland flow into lakes is reduced by the presence of forests.
Seepage has a smaller effect on water level than any other input.
(4. Why does the author use the phrase Note the word "net" in the passage^
To emphasize the impact of seepage on water levels
To point out that seepage is calculated differently from river flows and atmospheric exchanges
To compare the different methods of
The questions become more complicated when actual volumes of water are considered: how much water enters and leaves by each route? Discovering the inputs and outputs of rivers is a matter of measuring the discharges of every inflowing and outflowing stream and river.
Then exchanges with the atmosphere are calculated by finding the difference between the gains fro
